FILTER.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed. October 29, 1907. Serial No. 399,700.

To all whom it may concern:

Be it known that we, GILBERT H. EAsLEY and FLETCHER O. BUCKLES.,citizens of the United States, residing at Bristol, in the county ofSullivan and State of Tennessee, have invented new and usefulImprovements in Filters, of which the following is a specification.

This invention relates to, filters of that class which are used for thepurpose of filtering rain water in order to purify the latter before itsadmittance into a cistern or reservoir; and the principal object of thepresent `invention is to provide a filter having means for separatingand removing leaves and other vegetable matter and other grossimpurities from the water before the latter is permitted to pass intothe filtering compartment proper where such impurities wou d be liableto accumulate anddecay, thus impregnating water that may be subsequentlypermitted to pass through the filtering compartment.

Further objects of the invention are to simplify and improve theconstruction and operation of this class of devices. Y* Vith these andother ends in view, which will appear as the nature of the invention isbetter understood the saine consists in the improved construction andnovel arrangement and combination of parts which will be hereinafterfully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the accompanying drawing Figure 1 is a vertical longitudinalsectional view of a filter constructed in accordance with theinsurrounded by a fiange 4 which may be readily connected With a pipe orduct through which the water that is to be filtered and purified may beconveyed to the filter. Upon the front wall of the filter casing issecured a funnel-shaped compartment 5 having an exit aperture 6. A lidor cover 7 hingedly connected with the top flange 2 extends over theupper end of the body ofthe filter casing and also over the compartment5 for which a closure is thus provided.

In the upper end of the filter casing there is supported a trough orchute 8, the same being of a width equal to that of the filter casing inwhich the said trough forms a partition or diaphragm 3 this trough isdisposed in an inclined position, its upper end being arranged beneaththe inlet 3 and its lower end being arranged to discharge into thecompartment 5; the trough 8 has an aperture 9 formed directly beneaththe inlet 3, and this aperture may be covered or obstructed by a slideor valve 10 having at its rear edge a fiange 11 with which is hingedlyconnected a bail or handle 12 which latter extends through apertures ].3in the rear wall of the filter casing so that, when the valve is movedto an obstructing position above the aperture 9, the bail or handle maybe dropped to a non-obstructing position adjacent to the rear Wall ofthe filter casing as will be seen in dotted lines inFig. 1 of thedrawings. The sides 8a of the trough extend below the bottom thereof,and the trough is secured in applied po'sition by means of pins 8b.Screens 14 and 15 are secured to the sides 8a of the trough below thebottom thereof. The upper screen 14 is of relatively coarse and thelower screen is of relatively fine mesh, said screens or sieves beinginclined, as shown, and connected at their lower ends with thecompartment 5 into which material intercepted by said sieves willeventually be discharged. The trough 8 and the screens 14 and 15 may bereadily and quickly removed to permit the removal of filtering agentwithout disconnecting the casing 1. The withdrawal of the pins 8b willpermit the trough and the screens to be removed.

The bottoni of the filter casing has an outlet 16 surrounded by a flange17 with which a pipe or duct may readily be connected for the purpose ofconveying the filtered water to a cistern or reservoir; and the outlet1.6 is separated by a screen 18 from the body of the filter casing inWhich a packing 19 of charcoal or other suitable filtering material isplaced in the usual manner.

The o eration and advantages of the improved iter will be readilyunderstood from the foregoing description lwhen taken in connection withthe drawings. The impure water entering through the inlet 3 may, byobstructing the aperture 9 by means of the valve 10, be directed intothe compartment 5 and permitted to run to waste; this is usuallycontinued until the roof or other surface from which the water is takenhasbeen washed comparatively clean. The valve 10 is now moved to thenon-obstructing position shown in Fig. 1 of the drawings, kand watercoming through the inlet 3 will now pass through the aperture 9 vto thescreens or sieves 14 and 15 which will o eiate as strainers whereby thewater wil be freed from coarse and gross impurities still containedtherein before it is permitted to pass through the sieves into thefiltering compartment and thence through the exit 16 to the reservoirprovided for its reception. .The impurities intercepted by the screensor sieves will pass over the latter and into the compartment 5 and tothe waste pipe connected with said compartment.

The improved filter, as will be seen from the foregoing description, issimple in construction, and it will be found thoroughly efl'icient forthe purposes for which it is provided. By. the construction shown anddescribed, gross impurities of all kinds will be withheld from thefiltering compartment and the latter will thus be for a long periodmaintained in sweet and pure condition for effective operatio'n.

Having thus described the invention, what is claimed as new, is:-

1. A filter ofthe character described, comprising a casing `providedwith a lower filter ing compartment having an outlet, an upper receiving.compartment having an inlet, an external waste compartment incommunication with said casing, an inclined trough separating thefiltering and receiving compartments and having an opening in its upperend below the inlet and communicating at its lower end with the wasteycompartment, a closure for governing said inlet, and screens supportedby the trough and inclinedin arallel relation thereto and having theirower ends opening into the waste com artment, said screens beingsupported by tie trough and detachably mounted therewith for removalfrom the casing.

2. A filter of the character described comseazos closing both t ereceiving compartment and the waste compartment, an inclined' troughforming a partition separating the 'ltering and receiving compartmentsand provided at its upper end with an opening below the inlet of thelatter, the lower end of said trough being in communication through anopening in the casing with the waste compartment, means detachablysecuring the trough in position, whereby it may be detached and removedthrough the top of the casing closed by the cover, flanges dependingfrom the trough, and inclined screens supported by said flanges andcommunicating at their lower ends through the aforesaid 'opening withthe waste compartment, said screens being removable with the trough.

3. A 'Elter of the character described, comprising a casing having abottom iiltering compartment provided with an outlet, an upper receivingcompartment provided with an inlet,'and a waste compartment disposedexternally upon one side of the casing and in communication with anopening therein, a cover for closing both the receiving and wastecompartments, an inclined trough separating the filtering and receivingcompartments and having an opening disposed its upper portion below theinlet of the receiving compartment, said trough communicating at itslower end with the waste compartment and being provided with'dependingii'anges, inclined screens supported by said depending anges in parallelrelation to the trough and communicating at their lower ends with thewaste compartment, a closure for the opening in the trough slidablymounted upon the upper surface of 4the* trough, and an operating devicefor said closure pivotally connected therewith and slidably mounted inthe wall of the casing, the. construction being such that when the`closure is in obstructing position the operating device may be swungdownward on its pivot parallel with the wall of the casing.

In testimony whereof we afliX our signatures in presence of twowitnesses.
